Explanation:

edge

Answer 2

`x \geq -21`

Explanation:

Let the number be x.

Translating the word problem into an algebraic equation, we have;

`5(x + 27) \geq 6(x + 26)`

Opening the bracket, we have;

`5x + 135 \geq 6x + 156`

Collecting like terms, we have;

`6x - 5x \geq 135 - 156`

`x \geq -21`
